JOSEPH H. BnoMLEY, JR., or PHILADELPHIA, 'iENNSY LVANI A:

To all whom itmay concern:

Be it known that I,-Josarrr BRoMnEY,

Jr., a citizen of the United States, residing in the city of Philadelphia, State of Penn- 5 sylvania, have invented certain new and useful Improvements 1n Lace-Machines, of

which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings, forming a part of; this specification.

another s'et or sets of threads, in contradis-' tinction to ordinary weaving methods wherein the threads of one set are merely moved between and not around another and transverse set. To effect the action aforesaid in lace machines, the threadscontrolling jacks are required to be of such character as to present two thread-controlling surfaces, normally held out of operative planes, mounted to be independently moved, and actuated by mechanisms adapted to operate them accordingly. Such machines comprise mechanism for operating a setor sets of threads, a set of bobbin-carrying shuttles, mechanism for operating the shuttles with respect to the set or sets of threadsto-interlace the threads delivered from the bobbins with the threads of said set or sets, and a set of thread-controlling devices movable independently of each other and adapted to control the operation of said set or sets of threads with respect to the shuttles in accordance with a prescribed design to be produced in the; lace or product of the loom.

The object of the invention is to provide a novel," simple and efiicient means for selecting and controlling the thread-controlling devices including electric circuits and devices for opening and closing the circuits in accordance with a prescribed design.

lVith this object in View, the invention consists in the novel construction and combinations of parts-hereinafter described and pointed out in the claims.

Referring now to said drawings 3 designates the mainframeof the machine, and 5 "a supplemental frame adjacent the main frame. g

6 designates the main driving shaft which is journaled in suitable bearings in the main frame 3. The main frame 3 supports-a bar 8 which extends longitudinally of the ma .chine and is provided in itsupper portion with longitudinal parallel slots into which thread-guiding bars 9 and 10 are slidingly fitted; The n per portions of the bars 9 and 10 are provided with eyes or openings 11 and 12 respectively. The eyes 11 receive one set of threads 13 and the eyes 12 receive another set of threads 14. t

The threads 14 are drawn from a roll 72 to and through the eye 12 in the bar 10,

and thence to the lace being formed at the lower edge -15of a fixed bar 73, These threads 14 are commonly termed the warp threads, and they form the main structure of the lace.

The threads 13 are drawn from suitably supported spools 74 to and through suitable tension and take-up devices 75, thence to lace 76 passes over the bar 73 to and arounda roller 77 to a take-up roller 78.

- The set of threads 1'3 extends from the bar 9 to the bar73 through one plane, and the other set of threads 14 extends from the bar 10 to the ba': 73 through another, plane a slight distance from the plane of the threads 13 directly above the bars 9 and 10.

Supported by the main. frame of the machine directly above the bars 9 and 10 are two longitudinal comb bars 16 and 17, one arranged on one side and the other arranged on the other side of the sets of threads 13 and 14. These bars 16 and 17 are provided with transversely-arranged curved guideways 18 and 19 therein which are arranged parallel to and in line with each other. Slidingly fitted to these guide-ways 18 and 19 are the lower curved portions of a set of thin plate-like shuttles 20, each of which carries a flat bobbin 21 'from which a thread 22 is delivered tothe fabricor lace being produced by the machine. The shuttles 20 are arranged side by side, and the row or set of shuttles extends parallel to the two sets of threads 13 and -14. .The set; of shuttles 20 is adapted to be movedbodily through the planes of the two sets of threads 13 and 14 from the guide-ways'19'in the bar 17 to the guide-Ways 18 in the bar 16,

I and back again, in a manner to move the shuttles 20 and bobbins 21 carried thereby through and from side to side of the two sets of threads 13 and 14. For this purpose each shuttle 20 is-provided with a notch 23 on one side thereon and a notch 24 on the opposite'side thereof. The notches 23 are adapted to be engaged by a rib or tooth 25 on a longitudinal catch bar 26,; and the notches 24 are adapted to be engaged by a rib or tooth 27 on a longitudinal catch bar 28.

- The bars 26 and 28 are carried by arms 29 and 30- respectively, which are pivotally mounted on bell crank levers 31 and 32 respectively. The bell crank levers 31 and 32 are pivotally mounted on arms 33 and 34 respectively which are pivotally connected to' the main frame of the loom. The bell crank levers 31 and 32 are also connected to arms 35 and 36 respectively, which project from rock shafts 37 and 38 respectively, mounted in the main frame. The rock shaft 37 and 38 are provided witharms 39 and 40 respectively, which are connected by arms 41 and 42 respectively to the lower end of a lever 43 which is pivotally mounted on a shaft 44 on the main frame 3. The upper end of the lever 43 is connected by a bar 45 to a crank 46 on the main driving shaft 6,

whereby, during the; rotation of the main shaft, the lever 43 will be rocked back and forth, thereby rocking the bell crank levers 31 and 32 back and forth through their connections with the lever 43 and the main frame 3. This operation of the bell crank levers 31 and 32 moves the bars 26 and 28 toward and from the threads 13 and '14, and during the movement of the bars 26 and 28 they are raised and lowered on their pivotal connections with the bell crank levers 31 and 32 by rollers carried by the arms 29 and 30 and engaging cams 50 and 51 respectively. The timing of the bars 26 and 28 with respect" to each other is such that the bar 28 having its rib or tooth 27 engaged with the shuttles 20 will move the set of shuttles into and through the planes of the threads 13 and 14 from one side thereof, and after the shuttles have been projected through the planes of the threads the rib or tooth 25 of the-har'26 will en age,

thereof tothe other side of the planes of threads, while the rib or tooth 27 of the bar 28 is disengaged from the shuttles. Thus the shuttles 20 are moved from side to side of the sets of threads 13 and 14 during the operation of the loom. I

During the operation of the loom, the thread-guiding bars 9 and 10 are moved longitudinally in the slots in the bar 8 to shift the sets of threads 13 and 14Lwit-h respect to the shuttles-20, so that the shuttles 20, in passing from side to. side'of the planes of'the sets of threads 13 and 14 may pass-between different adjacent threads'of the two sets of threads each time the shuttles 20 are moved for the proper interlacing of the. bobbin threads 22 with the threads 13 and 14.

The bar 10 is connected to the upper end of a lever 52 pivoted to a bracket 53 on the main frame 3. The lower end of the lever 52 is provided with a roller 54 engaging a cam 55 on a shaft 56, whereby, during the rotation of the shaft 56, the lever 52 will be rocked in a manner to move the bar 10 longitudinally to shift the set of threads 13 with respect to the shuttles 20.

The shaft 56 is provided with a beveled gear wheel 66 which coacts with a sim1lar wheel 61 on a cam shaft 62 extending lon- 'the shuttles and complete the move ent gitudinally of the loom. The cam shaft 62 is provided with a gear wheel 63 which coacts with a similar wheel 64 on another cam shaft 65; The gear wheel 64 is in mesh with a gear wheel 66 on the main driving shaft 6, whereby, through the gearing just described, the cam shafts 62 and 65'are rotated and the cam shaft 56 carrying the cam 55 is also rotated.

The bar 9 is connected to the upper end of a lever 57 pivoted to a bracket on the main frame 3. The lower end of the lever 57 is provided with a roller 58 engaging a cam terlacing of the bobbin threads 22 with the spool and warp threads 13 and 14 respectively through the manipulation of the devices controlling said threads, the interlaced threads are beaten up to the lower edge 15 of the bar 73 bytwo sets of pins 79 carried by twolongitudinal bars 80 arranged parallel to the two sets of threads 13 and 14 and between 'which said threads pass. The bars 80 are, carried by suitable arms 81 which are operated to move the bars 80 in a manner to cause the rows of pins 79 carried thereby to be lowered and projected between the adjacent interlaced threads and then raised to beat up the interlaced threads to the lower edge 15 of the bar 73, and

then withdrawn therefrom. As rapidly as the interlaced threads are beaten up by the pins 79, the lace thus formed is taken up by the roller 78. The means for moving the point bars may be the same as those employed in many of the well known levers machine.

Arranged parallel to the sets of threads 13 and 14 and shuttles 20, is a set of threadcontrolling devices or jacks 67 for z the threads 13 and 14. These thread-controlling devices or jacks 67 extend upwardly, parallel to each other, from a bar 68, the lower ends of the jacks being secured to the bar. The set of jacks 67 is arranged adjacent to the bar 8 and the upper ends of the jacks 67 are extended toward the threads 13 and'14 above the bars 9 and 10,the up per ends of the jacks extending into guide slots on the bar 8. Normally, the upper ends of the jacks 67 are away from the two planes occupied by the two sets of threads 13 and 14, and the upper ends of the jacks are adapted to be projected into said planes as will be hereinafter described.

The bar 68 is mounted to be rocked on its is engaged by a cam 71 on the cam shaft 62, whereby, when the shaft 62 is rotated during the operation of the machine, the bar 68 will be rocked on its axis in a manner to project the upper ends of the jacks 67 into and through the two planes occupied by the two sets of threads 13 and 14.

The jacks 67 are made of spring metal, and each jack may be held independently of the other jacks against being projected into the planes of'the threads 13 and 14 during the operation of the bar 68, while the jacks not so held are being projected; or each jack may be arrested independently of the other jacks after its upper end has been projected into the plane of the set of threads 13 and before it has entered the plane of the set of threads 14.

The operation of the bar 68 with respect to the movement of the shuttles 20 and the bars 9 and 10 is such that the bar 68 is rocked to project the upper ends of the jacks 67 into the planes of the threads 13 and 14 before the bars 9 and 10 are moved to adjust the two sets of threads 13 and 14 with respect to the shuttles 20.

If all the jacks 67 be projected into the two planes of the two sets of threads 13 and 14, the movement of said threads under the influence of the bars 9 and 10 will be arrested by the engagement of the threads with the jacks. If, however, certain of the jacks 67 are prevented from being moycd by the bar 68 into either of the two plan-cs of the two sets of threads 13 and 14 or are permitted to be moved into the plane of the set of threads 13 and prevented from being moved into the plane of the set of threads 14, only such threads as are engaged by the DI'OjQCLQd jacks will be prevented from being moved by the bars 9 and 10 with respect to the shuttles 20. Thus it will be seen that the manner of interlacing the bobbin threads 22 with the spool and warp-threads 13 and 14 may be controlled by'the manipulation of the thread-controlling devices or jacks 67 in conjunction with the operation of the bars 9 and 10 as the shuttles 20 are moved from side to side of the two sets ofthreads 13 and 14 through the planes occupied thereby,

During the operation of the machine. the

bobbin threads 22 are wrapped around the spool threads 13 and the warp threads 14 in such a manner as to tie certain spool threads or figuring threads to certain warp threads and to tie certain warp threads together. Thus, plain or shaded figures may be pro- .duced in the lace by floating the spool or figuring threads between two or more adjacent warp threads 14 and tying the spoolthreads 13 to the warp threads 14 at each end of the float by the bobbin threads 22;

longitudinal axis, and the bar is provided or open work may be produced in the lace, wlth an arm 69 carrying a roller 70 wlnch l as IS common and well known in this art.

. tration thereof is deemed necessary herein.

' During the interlacing of the bobbin threads 22 with the two sets of threads '13 and 14, the bars 9 and 10 are, moved longitudinally back and forth to bodily shift the sets of threads 13 and 14 with respect to each other and to the shuttles 20, and certain or all of the jacks 67 are projected into design as dictated by the operation of the jacks 67; the jacks 67, by devices hereinafter described, being sellected and controlled independently of each other as to which jacks shall be projected into the planeof the set of threads 13 for the control thereof, which jacks shall be projected into the plane of the set of threads 14 for the control thereof, and which jacks shall not be projected into the plane of either set of threads 13 or 14 to permit certain of said threads to be shifted to the full extent with relation to the shuttles 20 by the operation of the bars 9 and 10. I

Thus far the construction and operation of the lace machine are common and well known and no detailed description or illusthread-controlling device 67 is a part or arm 82. The forward ends of the arms 82 are connected to the jacks 67, one arm to each jack, and the rearward ends of the arms 82 extend into and, are slidingly fitted to guide slots 83 cut in the top of a horizontal plate 84 which is supported onthe supplemental frame 5. The arms 82 are longitudinally movable independently of each other with the jacks 67, the rearward portions of the arms 82 being guided by the side walls of the slots 83.

The rearward end of each part or arm 82 extends downwardly and rests upon the bottom of its slot 83 and supports the main body of the arm 82 above the bot-tom of said slot. The downwardly-extending rearward end of each arm 82 provides two stop-engaging faces or abutments 85 and 86 which are located in different horizontal planes and also in different vertical planes transversely of the arm 82,- as shown in Figs. 4 to 6, for a. purpose hereinafter explained.

Directly under the rearward end of each arm 82 is a vertically-arranged tube 87, the upper end of which extends into an opening in the plate 84 and is suitably secured therein and electrically connected thereto. Each tube in a,two-part stop or pin 88. The upper end of the two-part pin 88 is flush with the bottom of the slot 83 containing the arm 82 directly above the tube 87, and the upper ,end of the pin is adapted'to be raised or projected into the slot 82 and into either the horizontal plane occupied by the abutment 85 or the horizontal plane occupied by the abutment 86. i r

The upper part 89 of the two-part pin 88 is movable independently of the lower part 92 of the pin, and isprovided with an'enlarged bottom port-ion 90 which is adapted to abut against a shoulder 91 within the end has been moved into the horizontal plane occupied by theabutment 85.

The lower part .92 of the two-part pin 88 is provided with an enlarged bottom portion 93 which is adapted to abut against a shoulder 94 within the tube 87 and limit the movement of the lower part 92 of the pin after it has moved the upper end of the upper part 89 into the;hor1zontal plane occupied by the abutment 861 A two-part pin is provided for each arm 82, and therefore a description of one will suffice for all.

The lower part 92 of the two-part pin rests normally upon a transverse pin 95 extending through the bottom of the tube 87, and theupper part 89 ofthe two-part pin rests normally upon the top of the lower part 92 thereof, with the top of the upper part 89 flush with or below the bottom of the slot 83 occupied by the arm 82 directly over the pin. It will thus be seen that the upper part 89 of the pin may be raised into engagement with the abutment 91 of the tube 87 independentlyof the lower part 92 to bring the upper end) of the pin into the horizontal plane occupied by the abutment 85 .of the arm 82, and that the raising of the lower part 92 of the-twopart pin into engagement with the abutment 94 of the tube 87 will also raise the upper part 89 of the pin to bring its upper end into horizontal plane occupied by the abutment 86 of the arm 82.

In order to raise the upper part 89 of the pin independently of the lower part 92 thereof, 1' provide an electromagnet in the form of a solenoid 96 which surrounds a portion of the tube 87 and the lower portion of the upper part 89 of the two-part pin 88, and which, when supplied with electric current, will raise the upper part 89 of the pin, independently of the lower part 92 thereof and into engagement with the abutment 91 of the tube 87 In order to raise the l wer part 92 of 'in Fig. 6, 'by the raising of the lower parts pins 88 of the arms 82ar'e down in the occupied by the set of threads 14. It will jacks maybe selected and held, independthe pin and thereby, raise the up er part 89 thereof to the extent to which the lower part 92 is raised, 1 provide an electromagnet in the form of a solenoid 97 which surrounds a portion of the tube 87 and the lower part 92 of the two-part pin 88, and which, when supplied with electric current, will raise the lower part 92 of the pin into engagement with the abutment 94 of the tu e 87. It will thus be seen that when the upper solenoid 96 is energized, the end of the upper part 89 of the two-part pin will be raised into the horizontal plane occupied by the abutment 85 of the arm 82, and that when the lower solenoid 97 is energized the lower part 92 of the two-part pin will be raised only a sufficient distance to raise the upper part 89 of the pin to bring its upper end into the horizontal plane occupied by the abutment 86 of the arm 82.

' The abutments 85 and 86 of each'arm' 82 are so located with respect to the two-part pins 88 for the arms and with respect to the planes occupied by the two sets of threads 13 and 14, that when the bar 68 is rocked to project the upper ends of the jacks 67' through the planes occupied by both sets of threads 13 and 14, each jack will be rojected into the planes'of both sets of t reads 13 and 14, if the two-part normal position shown in Fig. 4. If, howeye'r, the upper part- 89 of the two-part pm 88 of one or more of the jacks be raised to the position shown in Fig. 5, the pins so raised will engage the abutments 85' of the arms 82 and arrestthe'movernents of the jacks connected thereto against their own elasticity and prevent their upper ends from being projected into either of the two planes occupied, by the setsof threads 13 and 14, while the remaining jacks are projected by the rocking of the arm68 on into the plane or planes occupied by the two sets of threads 13 and 14. Or, if the upper end 89 of the two-part pin 88 of one or more of the jacks be raised to the position shown 92 of the pins, the pins so raised will engage the abutments 86 of the arms 82 and arrest the movements ofithe jacks connected thereto against their own elasticity, after their upper ends have been projected into the plane occupied by the set of threads 13, while the remaining jacks are projected by, the rocking of the bar 68 on into the-plane therefore -be seen that each time the bar 68 is rocked toproject the upper ends of the jacks 67 into the planes occupied by the two" sets of threads 13 and 14, certainof said ently fof each other and of the remaining jacks, against being pro ected into the planes 0 said threads, or projected only ace 8 into the plane occupied by the set of threads 13, while the remaining jacks are projected mto the planes occupied b both sets of threads 13 and 14, by supplying electric current to either one of the two solenoids 96 I shall now describe the means for automatically supplying electric current to the solenoids 96 and 97 for the selection and control of the jacks during the operation of the machine, in accordance with a prescribed design to be produced in the lace or product of the loom.

Supported on the supplemental frame 5 is a frame 98 including two vertical plates 99 and 100 arranged in spaced relation to each other. Extending horizontally through perforations in these plates 99 and 100 is a set of reciprocative pins 101 which extend beyond the outer faces of the plates. Arranged adjaceht one end of the set of pins 101 is a set of contact plates 102 corresponding in numberwith the pins 101. These contact plates 102 are secured to a plate 103 of insulating material which is secured to the frame 98 and which insulates the plates 102 from each other.

One contact plate 102 is in line with each pin 101, but normally out of contact therewith. The pins 101 are provided with transverse stop pins 104 which take against the plate 100 and limit the movement. of the pins.101 in a direction away from the contact plates 102. The pins 101 are pressed normally in a direction away from thecontact plates 102 by the action of springs 105 which encircle the pins 101 and bear against the late 100, and transverse pins 106 extendlng through pins 101. The pins 101 are longitudinally movable independently of each other so that any or all of the pins may be projected against the action of the springs 105 into contact with the contact plates 102. I

In rear of the set of pins 101 is an elongated square block 107 whichhis carried by a. shaft 150 journa'led in vertical plates 108 which extend downwardly from horizontal bars 109 arranged parallel to the pins'106 and slidingly fitted to, guide-ways in the frame 98. Pivoted to the bars 109 are the rearward ends of arms 110, the forward ends of which are pivoted to the upper ends of arms 111 and 112 which are fixed to a rock shaft 113 having its bearings in the frame 98. The arm 111 extends downwardly from the shaft 113 and is in the form of a lever, the lower end of whiclris pivoted to .an arm 114 extending from an eccentric strap 115 which surrounds an eccentric 116 carried by a shaft 117 journaled in bearings on the main frame.3. The shaft 117 is provided with a beveled gear wheel 118 which coacts with a similar wheel 119 on the upper end of an inclined shaft 120 which is journaled in bearings on the main frame 3. The lower end of the shaft 120 is provided with a beveled gear wheel 121 which coacts with a similar wheel 122 on the main driving shaft 6, whereby, during the operation of the loom, the rotation of the eccentric 116 will rock the lever 111 back and forth and thus rock the shaft 113 and cause the arms 110 to move the bars 109 back and forth, and thereby move the block 107 toward and from the rearward ends of the pins 101.

Extending over the block 107 and engaged with the upper and inner faces'thereof is a chain of jacquard cards 123 which are hinged together on their longitudinal meeting edges in the usual manner; The cards 123 are provided with perforations 124 which are adapted to be engaged by projections 125 on the block 107 to advance the chainof cards 123 when the block is turned to bringthe cards successively into proper registry with the faces of the block 107.

' tween which pins 152 extend, corresponding in number and position with the four cor- The shaft 150 carries two plates 151 beners of the block 107, as shown, and pivotally connected to the frame 98 as at 127 is oneend of a pawl, arm 128, the other or free end of which rests upon the pins 152.-

The free end of the pawl arm 128 is provided with a hook 129 which is adapted to engage the pins 152 successively and turn the block 107 a quarter turn each time the block is moved in a direction away from the pins .101. After the block 107 has been turned a quarter turn during the rearward movement thereof by the pawl arm 128, the block 107 comes to rest in the position shown in the drawings, in which the card 123 engaged with the forward face of the block is at right angles to the pins 101'; and the block 107 is held in this position during the forward movement of the block by the arms.

131 carried by and pivoted to the bars 109. Each arm 131 isdrawn downwardly by a spring 126 into engagement with a square block 153 carried by the shaft 150 and the engagement of each arm 131 with one face of its block 153 each time the block 107 is,

turned holds the block 107 in position. It will thus be seen that as thevblock 107 is moved toward and from the pins 101, the

cards 123 will be successively presented to the rearward ends of the pins 101. The jacquard cards are provided with the usual perforations 132 which are punched therein in accordance with a prescribed design, and which are located to select and receive certain .of the pins 101 while the remaining pins are engaged ,by the body of the card and projected thereby against the action of their springs 105 into contact with their contact plates 102, the ends of the pinsin line with.the perforations 132 in the card passing through the perforations and into openings 133 in the block 107 and being unaffected by the card. The openings 133 are provided in the four faces of the block 107 and they correspond in number and position with the rearward ends of the pins 101 as each face of the block 107 is presented to the pins. 7

Each solenoid 96 of each two-part pin 88 is included in an electric circuit which also includes one of the contact plates 102 and the contact pin 101 in line therewith, which circuit is adapted to be closed and opened I by the contact pin 101 being moved into and from engagement with the pin 102; and each solenoid 97 of each'two-part pin 88 is included in an electric circuit which also includes one of the contact plates 102 and the contact pin 101 in line therewith, which circuit is adapted to be closed and opened by the contact pin 101 being moved into and from engagement with the plate 102.

In Fig. 8 of the drawings '1 have shown, diagrammatically, the electrical connections 'for the two solenoids 96 and 97 of one twopart pin 88 for one arm 82 controlling one jack'67, the two solenoids being included in independent electric circuits which are closed and opened by two independent pins 101 making and breaking contact with two independent plates 102, and each arm 82 for each jack 67 is provided with a similar twopart pin 88 which is controlled by twov solenoids included in independent electric circuits which are closed and opened by two independent pins 101 making and'breaking contact with two independent plates 102. Therefore, the showing of the electrical connections of one'two-part pin 88 for controlling one of the jacks 67 will sutlice for all. Referring now to Fig. 8, one end of the solenoid coil 96 is connected by a wire 135 to a contact plate 102* (being one plate of the set of contact plates 102), the other end of the solenoid coil 96is connected to a wire 136 leading to an electric battery or source of electric current 137, and leading from the electric battery 137 is a wire 138 which is electrically connected to the plate 100 supporting the pin 101 electrically connected thereto, (which pin 101 is one pm of the set of pins 101), thus completing an electric'circuit for the solenoid 96 which may be closed and opened by moving the pin 101 into and out of contact with the contact plate 102;

One end of the solenoid coil 97 is con- 402), the other end of the solenoid coil 97 is connected to the wire 136 leading to the electric battery or source of electric current 137, and leading from the electric battery [[37 is the wire 138 which is electrically connected to the plate 100 supporting the pin 1.01 electrically connected thereto, (which :pin 101 is one pin of the set of pins 101), "thus completing an electric circuit for the solenoid 97 which may be closed and opened by moving the pin 101 into and out of contact with the contact late 102".

F or convenience of manufacturing and assembling the parts and making the electricalconnections for the solenoids, I inclose each pair of solenoids 96 and 97 for each two-part pin 88in a metal tube 142 which surrounds the solenoids 96 and 97 and is insulated from the central tube or solenoid core 87 by interposed top and bottom insu la'ting rings 134 and 140 respectively, and a central insulating ring 141 located between the two solenoids, the upper insulating ring 134 being provided with a contact rin 143 out of contact With the tube 142; an the whole being supported by the central tube 87, theupper end of which may be applied to and removed from the plate 84 as desired. The outer tube 142 is engaged by a contact spring 144 and the contact ring 143 is engaged by a contact spring 145. The contact springs 144 and 145 are mounted on an insulating plate 146 secured to the bottom of the plate 84, the plate 146 insulating the springs 144 and 145 from each other.

One end of each solenoid coil 96 and 97 is electrically connected to the central tube 87 which is electrically connected to the plate 84 which, in turn, is electrically conelectric current.

nected by a Wire to the electric battery or source of electric current 137. This electrical connection corresponds with the wire 136 shown in Fig. 8, connecting one end of each solenoid with the source of Each pair of solenoids for each two-part pin 88 is similarly connected to the source of current. The other end of the upper solenoid coil 96 is electrically connected to the ring 143 which is engaged by the contact spring 145 which, in turn, is connected by a wire to one of the contact plates 102, the ring 143, the contact spring 145 and the wire leading therefrom to a con tact late 102 corresponding with the wire 135 s own in Fig. 8. The other end of the lower solenoid coil 97 is electrically connected tothe outer tube 142 which is engaged by the contact spring 144 which, in

each solenoid coil 96 and-97 'of each twopart pin 88 is thus similarly connected to a contact plate 102, making an independent electric circuit for each solenoid which may be opened and closed by the pin 101 and contact plate 102 included in the circuit;

The timing of the shaft 117 with relation to the rocking of the bar 68 is such that before each rocking action of the bar 8 to project the upper ends ofthe jacks (37 into the planes of the two sets of threads 13 and 14, the eccentric 116 operates to advance the block 107 and the card on the front. face thereof into engagement with the set of pins 101, and a new jacquard card 123 is presented to the pins 101 each time the block 107 moves forwardly. Thus a jacquard card 123 having the perforations 13'2 therein acts upon the pins 101 and selects and operates certain of the pins 101, and closes the electric circuits controlled thereby each time the bar 68 is moved to project the jacks into the planes of the two sets of threads 13 and 14, and the circuits closed by the pins 101 will energize the solenoids included therein which, in turn, will operate the two-part'pins 88 controlled thereby and 'move said pins into-one or the other of the two horizontal planes occupied by the abut mcnts 85 and 86 of the arms 82 directly 'over said pins, and thus either prevent o limit the movement of ccrtain or all of the jacks (57 connected to said arms, while the remaining jacks are permitted to move into the planes of both sets of threads 13 and 14; the abutments 85 preventing the move-' ment of certain jacks into the planes occu pied by both sets of threads 13 and 14 and the abutments 80 permitting certainjacks 67 to be moved into the plane occupied by the set of threads 13 and preventing them from being moved into the plane occupied by the set of threads 14, in accordance with the operation of the two-part pins 88.

By the construction and operation of the parts hereinbeforedescribed, it will be s en that the design in the lace or product of the machine is controlled by the selection and operation of the jacks or thread-selmtting devices 67. It will also be seen that each jack is controlled independently of the remaining jacks by two electric circuit which are closed and opened independently of each other by two of the contact making and breaking pins 101; and it will also be seen that the jacks 67 are independently selected and controlled by operating the contact pins 101 independently of each olhcr and that the contact pins 101 are operated indc pendently of each other by the chain of jacquard cards 123. 'It therefore follows that if the chain of jacquard cards 123 be perforated in accordance with a prescribed design to be produced in the lace or prodnot of the loom, the pins 101 and perforce the jacks 67 will be independently selected and controlled in accordance with the perforations in the cards for the production of the desired design.

lVhile I have herein shown and described my invention in a desirable and practicable form, I desire it to be understood that I do not limit myself to this particular construction, as the same may be greatly modified without departing from myinvention; and particularly the automatic mechanism for closin and o enin the electric circuits in I accordance with prescribed design is capable of wide variation without departing from my invention.
